Here is an image showing the pin diagram of this transistor.The 2SC2497-R transistor can have a current gain of 80 to 160. The gain of the 2SC2497 will be in the range from 80 to 220, for the 2SC2497-S it will be in the range from 120 to 220.Sometimes the "2S" prefix is not marked on the package - the 2SC2497-R might only be marked "C2497-R".The complementary PNP transistor to the 2SC2497-R is the 2SA1096-Q.The FMMT451 (SOT-23) is the SMD version of the 2SC2497-R transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC2497-R with the 2SC2497A, 2SC2497A-R, 2SD1722, 2SD1723, 2SD1724, 2SD1725, 2SD794A, BD137, BD137-10, BD137G, BD139, BD139-10, BD139G, BD167, BD169, BD177, BD177-10, BD179, BD179-10, BD179G, BD189, BD228, BD230, BD235, BD235G, BD237, BD237G, BD377, BD377-10, BD379, BD379-10, BD787, BD787G, BD789, BD791, BDX35, BDX36, BDX37, KSD794A, KSE181, KSE182, KTC2814, MJE181, MJE181G, MJE182, MJE182G, MJE223, MJE225, MJE240, MJE241, MJE242, MJE243, MJE243G, MJE244, MJE721 or MJE722.
